The documentation is kind of unclear at that point. The
European/NonEuropean option (-e) controls

1) Whether the month is before the day or vice versa in the 'SQL' and
'Postgres' styles.

2) How ambiguous date input (e.g., 01/02/99) is to be interpreted
regarding month before day.

It does not affect the output of the ISO format, since the ISO format is
fixed.

PGDATESTYLE environment variable. Config file I'm working on.
